The EPOCH 600 is designed for use in nearly any inspection environment, from bench top testing in a laboratory to extreme outdoor and hazardous conditions. Designed for IP rating in either knob (IP66) or navigation pad (IP67) configurations, and tested to very high environmental and reliability standards, the EPOCH 600 allows users in any inspection environment to feel confident in both the performance and durability of the instrument. The instrument is tested for vibration, shock, explosive atmosphere, and wide temperature ranges. And with a battery life to exceed 12 hours, the EPOCH 600 is the perfect solution for remote inspection locations.

Vibrant Full VGA Display

The EPOCH 600 features a full VGA (640 x 480 pixels) resolution display. The horizontal design of the EPOCH 600 optimizes the A-scan size and readability on this high quality display. Built with transflective technology, this VGA display provides excellent clarity in indoor, low lighting conditions using its powerful backlight, as well as in direct sunlight by using the ambient light as a pseudo-backlight.

Optimized Access to Powerful Features

The EPOCH 600 provides excellent quality ultrasonic performance. Based on the same digital architecture as the EPOCH XT, LTC and EPOCH 1000 Series, the EPOCH 600 provides flexible, powerful pulsing and receiving features to accommodate the needs of most flaw detection inspections.

Pulser/Receiver

The EPOCH 600 comes standards with powerful flaw detection capabilities, such as:
• PerfectSquare™ tunable square wave pulser
• Digital high dynamic range receiver
• Eight 100% digital filter sets
• Auto or manually adjustable PRF from 10 Hz to 2000 Hz
• Pulser voltage from 100 V to 400 V
• Amplitude resolution to +/- 0.25%
• Five customizable digital measurements

Options for Comfortable Navigation

In order to accommodate different user needs and preferences, the EPOCH 600 is available in two hardware configurations: one with an adjustment knob and the other with a navigation area on the keypad. The adjustment knob and the arrow keys on the navigation pad are responsible for parameter adjustment and value slewing.

Knob

The adjustment knob on the EPOCH 600 is used along with the CHECK and ESC keys to adjust parameter values in either coarse or fine increments. You have the ability to lock the knob to prevent accidental parameter value changes during an inspection. This configuration provides smooth value slewing for customers who prefer adjusting parameters using a knob. The knob configuration is designed to meet the requirements of IP66.

Navigation Pad

The EPOCH 600 navigation pad is a hallmark feature of the EPOCH flaw detectors. The up and down arrows on the navigation pad are used for coarse parameter adjustment, and the left and right arrows for fine adjustment. The navigation pad also contains additional functions and frequently used parameters such as gain, save, and the CHECK and ESC keys. The navigation pad configuration is designed to meet the requirements of IP67.

Standard Software Features

EPOCH 600 DAC/TVG software screen

Dynamic DAC/TVG: Calculates signal amplitude as a percentage or decibel level compared to a DAC curve or a reference echo amplitude fixed at a time-varied gain. DAC versions include ASME, ASME 3, JIS, and Custom. Also includes several key features: dynamically adjustable DAC curves, switchable DAC and TVG views, and custom DAC warning curves.

DGS/AVG: This flaw sizing technique allows echo signals to be evaluated with a DGS/AVG diagram associated to a particular type of probe and material. The DGS/AVG diagram illustrates the relationships between echo height, flaw size, and distance from the transducer.

Curved surface correction: Corrects sound path information when using an angle beam transducer to circumferentially inspect a curved surface for either tubular or bar inspections.

Optional Software Features

AWS D1.1 and D1.5: Provides a dynamic reflector indication rating for various AWS weld inspection applications. This allows more efficient inspections by eliminating manual calculations.

EPOCH 600 software screen

Template Storage: Allows on-screen comparison of a live waveform with a saved reference waveform. Saved templates can be dynamically toggled on and off with a single key press for fast waveform comparison. Gain adjustment feature allows each saved template a unique base gain for inspections requiring varying sensitivity levels. Excellent for spotweld analysis and other applications.

API 5UE: Allows defect sizing according to API Recommended Practice 5UE. Uses the Amplitude Distance Differential Technique (ADDT) to measure the size of potential defects during the prove-up process of OCTG pipe. The measurement process is simple and repeatable since all ADDT variables are captured from a Peak Memory envelope.

Waveform Averaging: This feature allows the live A-scan view to represent an average of successively acquired A-scans. Waveform averaging improves signal-to-noise ratio when static flaws are detected. Averaging in 2X, 4X, 8X, 16X, and 32X.

Data Logging and PC Interfacing

Data Management

The EPOCH 600 allows several methods of storing, archiving and reporting inspection and calibration data. The instrument features up to 50,000 points of onboard memory, augmented by an additional 2 GB of removable memory. It is also fully compatible with Olympus NDT’s PC interface program, GageView™ Pro. With quick file setup functions and flexible data management, logging and reporting inspection data is simple and efficient.

GageView™ Pro

The EPOCH 600 is fully compatible with our PC interface program, GageView™ Pro. You can download inspection data, review measurements on a PC, export measurements and calibration data to common spreadsheet programs, back up calibration and inspection data from the instrument, and perform basic operations such as instrument firmware upgrades and screen captures.

GageView Pro software screen

Data Logger

The EPOCH 600 features on onboard data logger for calibration and inspection file storage. The instrument comes standard with two primary files types: calibration (CAL) and incremental (INC) files. CAL files allows you to save a virtually unlimited number of parameter setups for fast and easy recall to live settings. INC files store multiple pieces of inspection data under a single file name for downloading and reporting by inspection.

The onboard data logger can be enhanced to feature full corrosion-style data logger file types through the Expanded Datalogger software option. This option includes the following data file types: sequential, sequential with custom point, 2-D grid, 2-D grid with custom point, 3-D grid, boiler, 2-D EPRI.

MicroSD

The EPOCH 600 utilizes 2 GB MicroSD memory cards for both onboard and removable memory. Through removable memory, you are able to store screen images in bitmap format for easy reporting, as well as exporting current or saved measurement and calibration data in .csv format. A second 2 GB MicroSD card is mounted to the PC board inside the instrument, and is responsible for all onboard data storage. In the event the instrument is damaged beyond repair, this MicroSD card can be removed at an authorized service center, allowing the operator to recover critical data from the damaged instrument.
